Gurgaon's advertised prices are a total scam, change my mind.

Sector 91 & 92 mein Ganpati Builders ka project dekh raha tha. Matlab, brochure price kuch aur, final quote mein itne saare add-ons. I work in real estate, but buying for myself is different. Super area vs carpet area games toh chalta hi hai, but yeh PLC, parking, IFMS, electricity charges... sab milake almost 15-20% upar jaa raha hai. Builder bolta hai construction-linked payment plan best hai. Investors ke liye kya sach mein worth it hai? Ya direct down payment mein better deal milti hai? Kya koi hidden charges aur hain jo possession pe aate hain?
